Pyruvate decarboxylation or pyruvate oxidation, also known as the link reaction (or oxidative decarboxylation of pyruvate[1]), is the conversion of pyruvate into acetyl-CoA by the enzyme …

The link reaction refers to a stage in cellular respiration that “links” two other stages. The link reaction takes the products of the first stage, glycolysis, and converts them into reactants that will enter the …

Dec 6, 2025 · The link reaction, also known as pyruvate oxidation or the transition reaction, is a mandatory step in aerobic cellular respiration that acts as a bridge between glycolysis and the Krebs …

The Link Reaction is the first step in cellular respiration, occurring in the mitochondria of cells. It involves the transfer of electrons from NADH and FADH2 to the electron transport chain, producing ATP.

Jun 2, 2025 · Learn about the link reaction for your A Level Biology course. Find information on decarboxylation, acetyl CoA and NAD reduction.

In a series of enzyme-catalyzed reactions, glucose is phosphorylated (investment phase), then split into two molecules of G3P (cleavage phase). Then G3P is oxidized, which provides the electrons needed …

Nov 14, 2024 · Links glycolysis to the Krebs cycle by converting pyruvate into acetyl CoA in the mitochondrial matrix. Steps in the Link Reaction. Decarboxylation: Removal of CO₂ from pyruvate. …

The link reaction, which is sometimes called oxidative decarboxylation, takes place in the mitochondrial matrix. It connects glycolysis, which occurs in the cytoplasm, to the Krebs cycle, which occurs in the …

The link reaction is the step that connects glycolysis to the Krebs cycle in cellular respiration. It takes place in the mitochondrial matrix, where pyruvate (3C), the product of glycolysis, is converted into an …

As glycolysis splits glucose into two pyruvate molecules, the link reaction occurs twice per molecule of glucose.
